abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
Abstract One-class classification (OCC) is a fundamental problem in pattern recognition with wide range of applications. This work presents semi-supervised quantum machine learning algorithm for such problem, which we call variational one-class classifier (VQOCC). The suitable noisy intermediate-scale computing because the VQOCC trains fully-parameterized autoencoder normal dataset and does not...
مقدمه: سرطان اولیه کبد hcc)) پنجمین سرطان شایع در دنیا و سومین عامل مرگ و میر در جهان میباشد. علائم سرطان کبد پس از بروز به سرعت پیشرفت کرده و در صورت عدم تشخیص به موقع متأسفانه بقای عمر بیمار بسیار کم می گردد. یکی از مشکلات اصلی پیش روی متخصصین گوارش، پیش بینی و تشخیص زود هنگام سرطان کبد است. داده کاوی از روشهایی است که در این زمینه مورد استفاده واقع می گردد. هدف از انجام این مطالعه معرفی...
Deep neural networks have been shown to be very powerful methods for many supervised learning tasks. However, they can also easily overfit training set biases, i.e., label noise and class imbalance. While both with noisy labels class-imbalanced received tremendous attention, existing works mainly focus on one of these two biases. To fill the gap, we propose Prototypical Classifier, which does n...
One-class classification (OCC) poses as an essential component in many machine learning and computer vision applications, including novelty, anomaly, outlier detection systems. With a known definition for target or normal set of data, one-class classifiers can determine if any given new sample spans within the distribution class. Solving this task general setting is particularly very challengin...
Abstract: In disease gene identification and classification, users are only interested in classifying one specific class, disease genes, without considering other classes (non-disease genes). This situation is referred to as one-class classification. Existing machine learning-based methods typically use known disease gene as positive training set and unknown genes as negative training set to bu...
Distance classifier ensemble method based on Intra-class and Inter-class Scatter is proposed in this paper. By Bootstrap technology, the training samples are sampled repeatedly to generate several subsample set, define matrix with train set scatter matrix, individual classifier. In ensemble, results integrated relative majority voting method. Experiment tested UCI standard database, experimenta...
